Masteries problems in new champ select

1.) Selected mastery changing randomly between games. SOMETIMES the one that comes up when the champ select first opens is neither the mastery page i last used or one i clicked in a dodged champ select...it's just a totally random page. This is just particularly annoying if i go through several dodged games or i play the same thing a few times in a row and expect it to stay as the last selected one.

2.) New mastery page made in champ select does not show in list after it's saved and made. It will show up if you click the edit button but not be choosable in the list.

3.) A friend told me he repeatedly got an error box in one select when trying to click the masteries drop down list so he couldnt change it at all

4.) If you rename a page SOMETIMES the old name will show in the dropdown list but the new name will show in the edit page area.
